This situation can be directly operated without special requirements for the inventor. As for the change of the patentee, it is enough to submit a request for copyright change.
2. Hide the original inventor and only change the obligee.
When the obligee (applicant) changes, submit the inventor's change, but not the inventor's name information, only the inventor's public status, and submit the inventor's non-public statement.
3. Add inventors and change obligees.
Under the condition of keeping the original inventor unchanged, adding one or two inventors, especially in the case of one original inventor, adding two inventors to make the number of inventors after the change reach three, can also meet the requirements of inventors in some places.
